Toward Predictable Nanomedicine: Current Forecasting Frameworks for Nanoparticle–Biology Interactions

open access: yesAdvanced Intelligent Discovery, EarlyView.
Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...

Oxygen Activation by Mononuclear Mn, Co, and Ni Centers in Biology and Synthetic Complexes [PDF]

open access: yes, 2017
The active sites of metalloenzymes that catalyze O2-dependent reactions generally contain iron or copper ions. However, several enzymes are capable of activating O2 at manganese or nickel centers instead, and a handful of dioxygenases exhibit activity ...

A foundation for provitamin A biofortification of maize: genome-wide association and genomic prediction models of carotenoid levels. [PDF]

open access: yes, 2014
Efforts are underway for development of crops with improved levels of provitamin A carotenoids to help combat dietary vitamin A deficiency. As a global staple crop with considerable variation in kernel carotenoid composition, maize (Zea mays L.) could ...

Genomic variations associated with attenuation in Mycobacterium avium subsp paratuberculosis vaccine strains [PDF]

open access: yes, 2013
BACKGROUND: Mycobacterium avium subspecies paratuberculosis (MAP) whole cell vaccines have been widely used tools in the control of Johne's disease in animals despite being unable to provide complete protection. Current vaccine strains derive from stocks

Production of maleylpyruvate and fumarylpyruvate

open access: yes浙江大学学报. 农业与生命科学版, 2005
Gentisate 1,2-dioxygenase (GDO, EC1.14.13) from Klebsiella pneumoniae M5a1 successfully converted gentisate to maleylpyruvate. This biotransformation was performed by using genetically engineered E.

Substrate Oxidation by Indoleamine 2,3-Dioxygenase

open access: yesJournal of Biological Chemistry, 2015
The kynurenine pathway is the major route of l-tryptophan (l-Trp) catabolism in biology, leading ultimately to the formation of NAD+. The initial and rate-limiting step of the kynurenine pathway involves oxidation of l-Trp to N-formylkynurenine.

Obesity and cancer: existing and new hypotheses for a causal connection [PDF]

open access: yes, 2018
Existing explanations of obesity-associated cancer emphasise direct mutagenic effects of dietary components or hormonal imbalance. Some of these hypotheses are reviewed briefly, but recent evidence suggests a major role for chronic inflammation in cancer
